Although various methods are available to measure particle size distributions for a wide range of sizes and concentrations, most of them are best suited to relatively simple systems, i.e. one type of particle in a one or two component dispersion medium. However, real systems are often more complex containing different materials and shapes of particles and stretch the limits of commercially available instruments. In combination with imaging techniques and their analytical capabilities these instrument limits can be extended to gain a better understanding of the systems. To illustrate this, one example where the addition of TEM and EDX methods allowed the study of a complex, environmental sample will be presented.
